An improved method for protein crystal structure visualization

X-ray crystal structure visualization technique has been known for over a hundred years. While it keeps improving, it is extremely difficult to focus rays on objects that are invisible to the naked eye, such as proteins. ...

Researchers reveal a wide band gap topological insulator

Since their discovery in 2006, topological insulators have been widely discussed as a promising avenue for energy efficient electronics. Their unique high-mobility edge states have a form of "quantum armor" that protects ...

Crystal structure

In mineralogy and crystallography, a crystal structure is a unique arrangement of atoms in a crystal. A crystal structure is composed of a motif, a set of atoms arranged in a particular way, and a lattice. Motifs are located upon the points of a lattice, which is an array of points repeating periodically in three dimensions. The points can be thought of as forming identical tiny boxes, called unit cells, that fill the space of the lattice. The lengths of the edges of a unit cell and the angles between them are called the lattice parameters. The symmetry properties of the crystal are embodied in its space group. A crystal's structure and symmetry play a role in determining many of its properties, such as cleavage, electronic band structure, and optical properties.
